That is true. Apple macs are designed for 3d rendering but they are expensive. The best thing to do is to build a pc with a core i7, atleast 8gb memory, a gpu that is 256bits gddr5 and a 64bit os to make use of the 8gb memory.
That cpu is not good for 3d rendering. You should find something with 4 cores like Intel i5. Even Amd will be better for 3d and be even cheaper than intel..
